According to road safety charity, Brake, probably far more often than you'd like to think.
The group estimates that a huge 22 per cent of all crashes are caused by driver inattention.
A new car, however, hopes to solve this problem by using a driver's brain waves to start the engine and keep it going.
The car features a neuro headset that connects brain activity to the car’s engine through customised software.
The headset has 14 sensors detecting electrical activity from the frontal, temple, parietal and perceptual areas of the brain.
The amount of activity in these areas registers what the driver is cognitively processing, or if they are zoning out.
When the driver is distracted, the software sends a cut-off signal to the car and the accelerator switches to idle safely slowing the car down.
The headset can tell whether a driver’s attention goes from the road to the radio, when their neural activity dips, or when their blink rate slows significantly.
A gyroscope in the headset can also detect when a driver significantly turned their head away from the road.
